SLEIGH ATTACHMENT FOR WHEELED VEHICLES.

SPECIFICATION forming part of Letters Patent No. 509,786, dated November28, 1893. Application filed March 30, 1893. Serial No. 468,373. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE P. ASKIN, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Bob-Sled Attachments forWheeled Vehicles, of which the following is a specification.

The nature of my invention relates to an improvement in sled-bobs of theclass that is used for replacing the wheels on the axlearms of a vehiclewhereby the latter may be advantageously used on snow or ice, and itsobject is to make a stronger, lighter and cheaper construction thanshown in the various devices now used for the purpose.

To this end my invention consists in making the bob proper from a singlebar of steel bent, formed and riveted, as morefully hereinafter shownand set forth.

Figure 1 shows mybob in perspective. Fig. 2 is a perspective Viewlooking at the same from underneath.

In the drawings-A is the bob, and B a wooden hub, securely fastenedthereto by the U-shaped clips, 0, G.

In the manufacture of the bob, commencing at a a right angle bend, b, ismade edgewise, extending backward, parallel with the bobbody for abouteight inches, and forming the outer bed for the hub; a semicircularbond, 0, is then made edgewise in the bar, which then continues forwardhorizontally, until nearing the toe, when it curves slightly upward; atthe toe a loop, d, is formed, in which a checkring, e, may be placed toreceive the usual check-strap. From the toe, the runner part is bentdownward with the usual curve, the bottom part being straight formingthe runner,f; at the rear end or heel the bar is bent fiat upon itself,and the double part is curled up to form the heel, g; a countersunkrivet at It may be used to fasten the doubled parts together. The bar isthen bent diagonally upward and forward until it reaches the rear end ofthe inner hub-bed at 4), extending thence horizontally forward to j,where it is bent diagonally forward and downward to the runner at it,its foot extending forward thereon, and is firmly fastened thereto bytwo countersunk rivets, Z, Z. The end d islikewise riveted to thetop-chord, as is also the horizontal upper part of the brace-panel, thusstrengthening greatly that part of the bob subjected to the greateststress and strains. The hub has a taper bore to receive the axle-arm, onwhich it is held by the axle-nut.

I do not wish to confine myself to the employment of a wooden hub, as itis evident that metallic hubs may be used, and also that such hubs maybe adjustable to fit axle-arms of various sizes, and further they may besecured to the bob otherwise than with clips.

The eye in the toe, and the curl in the heel of the runner may bedispensed with, without departing from the spirit of my invention.

When the bottom or runner of my bob is worn thin, a shoe can be readilyriveted thereto, using the same holes for the new rivets.

What I claim as my invention is- 1. A sleigh bob formed of a singlepiece of flat metal and consisting of the lateral extension forming thehub bed, the bob parallel therewith, the runner and the bracesconnecting the bob and runner.

2. A sleigh bob formed of a single piece of metal, formed first toprovide the lateral extension, next the bob parallel therewith,then

the draft eye; then the runner and terminating in the inclined bracesconnected to the bob and finally to the runner and the hub secured onthe extension.
